SELF-INKING HAND STAMP AND DATER COMBINED. v

SPECIFICATION forming part of Letters Patent No. 297,856, dated .April 29, 1884.

` Application tiled June 5,1882. (No model.)

To all whom, it may concern:

Be it known that I, ERNST SCHMITZ, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Self-Inking Hand Stamps and Daters Combined; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, illustrating the improvement, in which- Figure I, Sheet 1, is a central sectional elevation of a mechanism embodying' my improvements; Fig. II, a vertical sectional elel vation ofthe device on line fr, Fig. I, looking in the direction indicated by the dart z; Fig. III, Sheet 2, a plan view of the frame which is employed to raise the dating-dies to change the dates; Fig. IV, an end elevation of the stamp; Fig. V, an inverted view of the stamp; Fig. VI, an elevation of one of the numberingwheels removed from the other parts.

The nature of the present invention consists in the novel construction of the dater-wheels and mechanism for operating them in connection with a printing-die, asV hereinafter more fully described and shown.

A represents the ordinary frame of a handstamp. It is formed so that only the top and ends shall be closed, the bottom being held in place by rods K K.

rIo the under side of the horizontal part of the frame is attached the ordinary inking-pad, I. The frame is also provided with the ordinary standard, W.

B is the frame, which is operated by the han'- dle C to put the die alternately to the inkingpad I and to the material to-be stamped.

The bearings a for the guide-pins b are slotted transversely to the frame B, and form a part of the mechanism for operating the die; but this construction of frame or yoke arms is not claimed to be new, and is not an essential part of the device, inasmuch as my diewheels can be properly operated by Several of the plunging frames or yoke-arms well known to the art.

M N are the Wings of the die supporting the4 pin b. The wing N is slotted out vertically from o to o, as shown at Fig. I, to receive a guide-pin, It, which is attached to and pro- 5o jects inward from the frame A, whereby the diefplate I is held in position to have the proper reverse movement from the inking-pad I tothe surface of the material to be stamped. The particular location of the pin R is close to the slot c and on the Widest part of the metal at the middle length of the Slot. Both slots c should have the same curve in the vertical parts or ends of the frame A; and affixed to said ends closely to the vertical parts of the 6oL frame B are guide-pins w, to hold the frame B in position relative to the slots a a c c. Now, by means of these slots and pins,when the handle C is forced down, as shown at Fig. I, the die-plate I will be brought face downward, as A shown, from the position it is in to'be inked. (See Figs. 2 and 4.)

Projecting out from the back ofthe dieplate I are two square posts, H H', ,and placed thereon by means of suitable mortises is a 7o `frame, z x, the parts z supporting springs u,

and the parts :ma supporting a cylinder-shaft, c, on which the numbering-wheels are placed. These wheels are shown at L P S D, and consist each of a cylinder-box, E, which may be .turned on the shaft V, and of a rubber diewheel attached to the box, by means of which the wheels may be turned to change the date without detaching any of the parts; and the wheels are made very durable and free from 8c friction by means of the metal washers f f f, obvatin g the difficulty of turning rubber bearing against.rubber without its being drawn out of shape. Each wheel is formed with any number of radial dies suitable to make the required dates. One radial die on each wheel projecting through the die-plate I, as shown at Figs. I and II, forms the desired date.

On the ends of the radial arms of wheel D are to be formed the figures of the years, on 9o wheels I? S the gures for the days of the months, and on the wheel L the names of the months. From this it will'be 4seen that the wheels have the Same movement that the die has-that is, they are turned half round and back again with it-and that on the face of the die-plate. a rubber die formed to stamp or print other matter may be attached.

The means for elevating the frame z so as to bring the arms of the die-wheels L P S D out of the slot in the die-plate at I and above the plate, so that the die-wheels may be turned on the shaft o to change the dates, consists of lever F G G, (shown at Figs. II, III, IV, and V,) which is provided with jaws r 7' at the ends of the arms, to pass onto the sides of the posts H H, under the frame z, and above the die-plate I, and provided with slots d d in the arms, to receive pins e e, which project up through the slots Vfrom the die-plates. The arms G G are curved upward from the jaws r 1', so as to have a proper fulcrurn on the plate I; and the slots d (l are cut long enough to allow the lever to have a sufficient movement, but not so long as to permit the jaws r r to move from under the frame z or away from the posts H. To elevate the die-wheelspress down on the bar F of the lever. To hold the die-wheels to their work when not acted on by the lever, coilsprings a a are placed on the posts H H and between the caps J and the frame z.

In the foregoing I have described a complete handstamp and die attachment; but I confine myself to the elements claimed.

I disclaim the handle having yoke-arms with Wardlyextending pins, in combination with the oscillating die-plate provided with studs extending through the two sets of slots, and with ears adapted to engage the pins so as to oscllate the die-plate, as I am not the inventor thereof.

I claim and desire to secure by Letters Patentl. The rubber die-wheels L l? S D, provided with metal boxes E, in combination with the round shaft o, as specified.

2. The combination of the rubber die-Wheels L P S D, boxed as stated, with the washers f f f, to separate the rubber, as and for the purpose specified.

3. The combination of the frame z ac, for supporting the die-wheel, with the die-plate I, posts H H, and springs 1L n, as and for the purpose specified.

4. The combination of the 'lever FG 1' o', constructed as described,\vith the rubber diewheels, frame z x, and shaft o, as specified.
